How do i fix a cb radio tube type has no receive

you have to have a vtvm a schematic of the radio and a replacement tube if necessary .With these tube types be very careful not to touch anything you shouldn't because you could get a terminal shock. with the schematic check the voltage spec and make sure the tube is actually working properly ,then check the socket to make sure that the correct voltage is getting to it Make sure you don't have any static because it will short out the radio.

Finding Marconi radio schematic model79-c

If it is a 791 instead of a 79, check here:

you may find a similar model.

If it is a Marconiphone,
Although there were some Marconi models that may not be int he Nostalgia Air database for any number of reasons, partly due to the fact Rider usually put them in with the Miscellaneous models.

Other possible sources could be in the various "Shortwave guides" that were published in that era- many included schematics from the manufacturers. Lindsay publishing has reprinted 1936 and 1937, whether they are still available is tough to say, but you can check the listing of what Lindsay publications has on hand at just look for the book list.

My own suggestion- Recap it completely first. Then check the resistors to make sure none are outside of the tolerances- usually 20 percent. From there, tweak the IF;s and the radio should come to life even with weak tubes.

If you are in the UK, or Europe, there should be a few dedicated museums that may have the schematic available as well- just use search engines less used. In other words- forget google or bing- Although or might give you some hits if the radio is not of US manufacture.

I have a Westinghouse tube radio, AM/FM table model, uses a selenium rectifier. I need a schematic for this radio, do not have a model number, but chassis number is 240635. Would appreciate your help.

Hi driggins

Wondering if that may be the serial number that you have quoted. Most Westinghouse radios that I have been able to find are allocated model numbers as WRXXX
If it has a solid state rectifier then it will be post war vintage at least.

Are there any other identifying marks on the radio?

I need a scamatic for a teberry stalker xv cb radio

I assume you have already checked out cbtricks..... they have about 20 or so teabery schematics/mods and whatever there.... possible they don't have yours.

I have a bunch of old Sams photo fact manuals around the shop here.... all of the Sams I have are all old radios... mostly tube. So there is a chance I might have a Sams photofact that has your model in it.

So if your really stuck.... I might be able to take a look what we have here and scan a copy for ya.

I'll take a quick look on line at a few schematic website I use regularly and see if I can find a pdf for your radio.
If your really stuck ... I can look through those sams we have here .
Let me know.
